Information processing device, information processing system, and network communication confirmation method

1. An information processing device, comprising:

a memory; and

a processor coupled to the memory and configured to:

store, in the memory, a confirmation program for performing communication confirmation of a network,

transmit the confirmation program to a server in the network,

collect, before the network is constructed, from the server, an execution result of the communication confirmation obtained by causing the server to execute the confirmation program for the communication confirmation, and

perform correctness determination of the execution result.

2. The information processing device according to claim 1 , wherein the processor is configured to:

store a table illustrating a communication state for correctness determination in advance, and

perform the correctness determination by collating the collected execution result with the table.

3. The information processing device according to claim 1 , wherein the processor is configured to perform the communication confirmation via the temporary address by allocating a temporary address not overlapping with another server to an additional new server.

4. The information processing device according to claim 1 , wherein the processor is configured to:

transmit an operating system (OS) for executing the confirmation program to an additional new server,

transmit the confirmation program to the OS, and

cause the new server to execute the communication confirmation.

5. The information processing device according to claim 1 , wherein the processor is configured to:

be connected to a management network used for system management and to a business network used when operating a business via a switch, and

execute confirmation of a first communication state between the server and the management network and a second communication state between the server and the business network using the confirmation program.

6. The information processing device according to claim 5 , wherein the processor is configured to

execute confirmation of a connection state between the server and the management network, a state in which the server is one-side connected with the management network, and a communication band state between the server and the management network, as the first communication state.

7. The information processing device according to claim 5 , wherein the processor is configured to when the management network includes a migration network for migrating a virtual machine in the server and a storage network for operating a storage in the server, execute confirmation of presence or absence of a setting for the migration network for the switch and presence or absence of a setting for the storage network for the switch, as the first communication state.

8. The information processing device according to claim 5 , wherein the processor is configured to execute confirmation of a connection state between the server and the business network, presence or absence of a setting for the business network for the switch, and a communication band state between the server and the business network, as the second communication state.

9. The information processing device according to claim 1 , wherein the processor is configured to execute confirmation of an unusable state of a network service using the confirmation program when an external server for performing the network service is connected to the network.

10. The information processing device according to claim 9 , wherein

the external server includes at least one of a domain name system (DNS) server, a network time protocol (NTP) server, or a dynamic host configuration protocol (DHCP) server,

wherein the processor is configured to:

execute confirmation of a state whether name resolution execution is executed by the DNS server as the network service in a case where the DNS server is connected to the network,

execute confirmation of a state whether a time synchronization is executed by the NTP server as the network service in a case where the NTP server is connected to the network, and

execute confirmation of a state whether an internet protocol (IP) address allocation is executed by the DHCP server as the network service in a case where the DHCP server is connected to the network.

11. The information processing device according to claim 1 , wherein the processor is configured to collect the execution result of the communication confirmation transmitted from the server by causing the server to execute the confirmation program by transmitting the confirmation program.

12. The information processing device according to claim 2 , wherein the execution result of the communication confirmation is obtained by causing the server to execute the communication confirmation program based on table includes items of communication confirmation regarding the network.

13. An information processing system comprising:

a server that includes a first memory and a first processor coupled to the first memory; and

an information processing device that includes a second memory and a second processor coupled to the second memory, wherein

the first processor is configured to specify an execution result of communication confirmation of a network by using a confirmation program for perform the communication confirmation, and

the second processor is configured to:

collect, before the network is constructed, from the server, the execution result obtained by causing the server to execute the confirmation program for the communication confirmation, and

perform correctness determination of the execution result.

14. A network communication confirmation method executed by a computer, the network communication confirmation method comprising:

storing, in a memory, a confirmation program for performing communication confirmation of a network,

transmitting the confirmation program to a server in the network,

collecting, before the network is constructed, an execution result of the communication confirmation obtained by causing the server to execute the confirmation program for the communication confirmation, and

performing correctness determination of the execution result.
